LAURANT B. WILKINSON BY M M li tr ATTORNEYS United States Patent PREFABRICATED SLIDING WINDOW BUILDING CONSTRUCTION UNIT George E. Ryan, Inglewood, and Laurant B. Wilkinson, Los Angeles, Calif., assignors to New-View Window Company, Inglewood, Calif., a corporation of Callfomia Application June 1, 1954, Serial No. 433,624

1 Claim. (Cl. 20-52) This invention has to do with building construction, and relates more particularly to a sliding window building unit.

It is an object of my invention to provide a building unit of this character which may be easily secured between a pair of wall uprights or studs, after which the building walls may be constructed about the unit.

It is another object to provide a prefabricated sliding window building unit which is economical both to construct and install.

It is a still further object to provide a prefabricated unit of this character which is of such construction that a metal frame which provides tracks for the slidable sash may be flushly mounted in a surrounding wood frame.

Other objects and advantages will become obvious from the following detailed description of a presently preferred embodiment of my invention, for which purpose I shall refer to the accompanying drawing wherein:

Fig. 1 is a side elevation of a unit embodying my in-' vention, as viewed from the inside of a building in which it is mounted;

Fig. 2 is an enlarged section taken on line 2-2 of Fig. 1;

Fig. 3 is an enlarged section taken on line 3-3 of Fig. 1;

Fig. 4 is an enlarged section taken on line 4-4 of Fig. 1;

Fig. 5 is an enlarged section taken on line 5-5 of Figs. 1 and 4;

Fig. 6 is a view taken on line 6-6 of Fig. 5; and

Fig. 7 is an enlarged section taken on line 7-7 of Fig. 1.

Referring now to the drawings, my unit generally denoted by the numeral 5, comprises a rectangular frame 15, preferably of wood, although other suitable materials may be used, having an intermediate vertical cross member 16.

The frame 15 has an inner width of two window openings A and B, and, on its outer side, the left side in Figs. 2 and 3, it has recesses 17 and 17 bounding the respective window openings. In recess 17, I may mount a fixed glass window pane 20, secured in position as by putty 21, while in recess 17 I may mount a conventional screen frame 18 carrying a conventional window screen 19.

As best shown in Fig. 4, the cross member 16 is relatively thinner than the remainder of the frame 15 so that its inner surface 16a is in a plane outwardly offset from the plane of the inner side surface of frame 15, thus providing, inwardly of the cross member 16, an opening 22 substantially co-extensive with the size of both window openings, for the reception of a second frame 30.

Frame 30 is preferably, though not necessarily, made of aluminum or other suitable metal and is generally U- said slideways being opposed and parallel. The frame 30 is composed of walls ,34, 35 and 36. Wall 36 has a rib 37 extending about its perimeter, which rib projects into a groove 25 formed in the frame 15 around opening a filling of grout 38 being inserted in the groove 25 abpnt 11. ,rib 37 to provide a watertight seal between frames 30 and 15.

Frame 30 also has a flange 40 extending about its perimeter and bearing against the inner side surface of the frame 15 around the opening. Screws 41 further secure the frame 30 in opening 22.

A sash 45 of channeled cross-section is slidably mounted in the slideways 32, 33 so that it may slide between a position opposite the window opening A and a position opposite the window opening B, and vice versa. The sash 45 preferably has a reinforcing wood core 50, and carries a glass pane 47.

Extending along its right hand edge, the sash 45 has a flange 51 which is positioned to abut the cross member 16 when the sash is in closed position opposite the window opening A (Fig. 1), in which position the said flange also serves the additional purpose of a weather strip; and has a flange 52 which functions as a pull bar to facilitate manually sliding the sash along the slideways.

The sash 45 is of a height sufficiently less than the distance between the opposed walls 36 of the slideways to provide a clearance between the top edge of the sash and the top wall 36 at least equal to the depth of slideway 33 to permit the sash to be lifted upwardly into the slideway 33 while the bottom portion of the sash is laterally swung inwardly of the building to remove it from the frame 30 when it may be desired to repair or clean thev sash or to replace a sash with another.

For the purpose of locking the sash in the closed position of Fig. 1, I provide a locking pin 60 having a knurled outer end portion, and having a cross pin 62 at its inner projecting end portion arranged to engage in a bayonet slot 63 in cross member 16; the pin rotatably extending through a hole 64 in the sash. Thus, the pin may be moved into locking position by rotating it clockwise to engage the cross pin in the slot.

The sash 45 is preferably provided, at least along its bottom edge, with conventional self-lubricating nylon glide members 70, which engage the wall 36 along the bottom of slideway 33 to prevent metal-to-metal contact. Preferably the glide members are slightly wider than the sash so as to prevent frictional sliding engagement of the side surfaces of the sash with the side walls 34, 35 of the frame 30. I may also mount such glide members along the top edge of the frame 30 to prevent metal-to-metal contact of the side surfaces of the top portion of the sash with the frame 30.

To mount my unit, the frame 15 is nailed to the building studs 75, and then the exterior building side wall surfacing (not shown) may be applied so that the frame 15 will be substantially flush with the outer surface of said wall surface.

We claim:

A prefabricated window unit for a building having spaced upright frame members, said unit comprising a wood frame of a length coextensive with the spacing of said frame members and arranged at its ends to be secured to said frame members, said frame having top, bottom and side portions, a cross-member secured at its ends to said top and bottom portions and defining with said frame a pair of horizontally juxtaposed window openings, closure members rabbeted in the outer portions of said frame in covering relation to said openings, said cross-member having its inner surface outwardly offset from the plane of the inner surface of said frame whereby the inner portion of said frame inwardly of the inner surface of said cross-member defines a space equal to the combined area of said openings plus the inner surface area of said cross-member, the top and bottom portions of said frame having longitudinal grooves opening into said space, a metallic subframe of channeled crosssection mounted in and coextensive with said space, the top and bottom portions of said subframe providing longitudinal slideways throughout their lengths, and a sash, of a Width substantially coextensive with the width of only one of said Window openings, slidably mounted at its top and bottom in said respective slideways; said subframe being of a thickness substantially equal the distance between the inner surface of said cross-member and the inner surface of said Wood frame, and having rib portions extending into said grooves.
